Airborne UAV survey

To reduce deviation interference, the magnetometer sensor is placed in a suspended gondola. The complex includes satellite navigation equipment (GPS + GLONAS), providing coordinate reference of measurement points (antennas are located both on the UAV and in the gondola).

Special software allows you to prepare a detailed flight mission taking into account the digital terrain model, which can be obtained by photogrammetry (processing of images obtained using UAVs).

UAV Features:

• multi-rotor unmanned aerial vehicle with a hybrid engine;
• application in any landscape-morphological conditions;
• speed - up to 50 km / h;
• flight duration - up to 5 hours;
• temperature barrier: - 20 ° С + 40 ° С

The main tasks to be solved:

• identification of ore deposits with favorable magnetic differentiation of rocks;
• mapping of different ranking zones of discontinuous violations;
• isolation of intrusive complexes of various compositions;
• allocation of zones of metasomatically altered rocks;
• mapping of buried paleodolines in order to predict placer deposits.

The main parameters of the magnetometer:

• Type: quantum
• Sensitivity: 0.6 pT
• Measuring Range: 15,000 to 105,000 nT
• Measurement frequency: 1000 Hz
• Range of allowable sensor angles: 10 ° to 85 °
• Operating temperature range: from -20 to +40 ° С
• Heading error: ± 0.25 nT

Advantages of the method:

• high measurement density along the profile - the distance between the samples is about 1 m;
• high accuracy of binding of measurement points and measurements themselves;
• uniformity of coverage of the work site;
• shooting with detailed flow around the relief at the lowest possible height;
• the ability to perform multilevel measurements in order to reduce ambiguity in quantitative interpretation.
